mill-jacoco - Coverage Reporting for Mill

Build Status (GitHub Actions)

Mill plugin to collect test coverage data with JaCoCo and generate reports.


You need at least Mill 0.9.7 to use mill-jacoco.

To enable coverage data generation with JaCoCo, you need to add the JacocoTestModule to your tests.

import mill._
import mill.scalalib._
import mill.define._

// Load the plugin from Maven Central via ivy/coursier
import $ivy.`de.tototec::de.tobiasroeser.mill.jacoco::0.0.3`
import de.tobiasroeser.mill.jacoco.JacocoTestModule

object main extends JavaModule {
  object test extends super.Tests with JacocoTestModule

To generate JaCoCo reports, run:

mill de.tobiasroeser.mill.jacoco.Jacoco/jacocoReportFull


You can download binary releases from Maven Central.

Please make sure to use the correct mill platform suffix matching your used mill version.

Mill is a Scala-based open source build tool. In my opinion the best build tool for the JVM. It is fast, reliable and easy to understand.


I’m a professional software developer and love to write and use open source software. I’m actively developing and maintaining mill as well as several mill plugins.
